Sample Preparation Subtopics

Introduction to Collecting Varian Data

September 09, 2020 03:41 PM
basic outline of procedure – chemistry computer account – VnmrJ – ejecting/inserting sample – sample holder – depth gauge – sample positioning (including Shigemi tubes)

VnmrJ Study Queue

September 09, 2020 03:41 PM
setup study (name, solvent, add spectra) – adjusting parameters – 2D digital resolution vs # t1 increments – submit sample (things to watch)

Using the AutoSampler

August 17, 2021 09:38 PM
interacting with the sample tray view – submitting/editing/deleting/continue studies to the sample tray – information regarding time limits for the Day and Night queues

Concentration Estimate

September 09, 2020 03:41 PM
estimating time based on concentration – estimating concentration from 1H spectrum – continuing a study – common problems (e.g., fixing red automation error messages)

Varian: Selective 1D & 2D Protocols

September 28, 2020 09:49 PM
1D-selective TOCSY and NOESY – band-selective HSQC and HMBC – running scout spectra – setting up selective protocols under automation – processing data
